STARTING DEVICE FOR EXPLOSIVE-IENGINES.

To all whom 'it may concern:

Be it known that I, HERBERT L. MEEDER, a citizen of the United States,residing at Fremont, in theV county of Dodge and State of Nebraska, haveinvented certain new and usefulI Improvements in Starting Devices forExplosive-Engines; and 1 do declare the following to be a full, clear,and exact description of t-lie invention, such as will-enable othersskilled in the art to which .it appertains to make and use the same.

This invention relates to starting devices for explosive engines.

One object of the invention is to provide a` device of this character bymeans of which the cylinders of an explosive engine may be primed Aorcharged and the engine 4thus started without-'the usual crankingoperation.

J'Another object is to provide a-` priming or charging mechanism forexplosive engines having an improved construction and arrangementof'fuel compressing and mixing mechanism and an improved-meansfor't'oicing the charge of fuel mixed by said mechanisml into thecylinders of the engine wherein the charge is ignited and exploded by avsuitable `sparking mechanism. thus starting tlieengine. A furtherob'ectis to provide a starting device of Athis character which isparticu- 1 larly adapted for vuse in connection with the engines ofmotor ,vehicles and which may be arranged within convenient reach oftheoperator from the seat of the. vehicle.

through the fuel inlet valve casing of one of thel motor cylinders.

n the embodiment 'of the invention, I provide-a plurality of fuelcompressing or pumping cylinders 1, one o'f which is provided for eachcylinder of the engine or motor with which the device is connected. Thecylinders 1 arearranged on a suit-able base and whenemployedinvcoiinection with the engine of a motor vehicle as shown in theaccompanying drawings, the base Q is secured to the floor or frame wo-rkof the vehicle and may be arranged beneath the hood, or, as shown in thedrawings, may he arranged adjacent to the inner side of the dash boardand in front of the chauffeurs seat. Y The upper ends ofthe cylinders 1are closedby a top plate 3 and in the cylinders are arranged pistons 4having piston rods 5 which work through stuffing boxes arranged in theplate 3 and are Aconnected at their upper ends by a, spider Glwlierebythe pistons are operated-in unison. i

Mounted in a suitable bracket 7 arranged on an extension ofthe baseplate 9. is a hand lever 8 having on its lower end anangular'operating.bar 9, the outer end of which is connected by a link10-with the center of the spider 6 whereby the latter is moved up anddown bv t-he lever to reciprocate the pistons 4. The link 10 and outerend of the bar 9 are adapted to work through a slot 11 formed in the topplate 3v of the cylinders as clearly shown in Fig. Q,

engaged a check valve 13 whereby the ports- 12 are normally closed.Connected with the casings ofthe valves 13 are fuel conducting pipes 14which lead to and are con-- nected withcheck valve casings '15arrangedon and connected .with the upper'end of each of the cylinders asshown. In the casings 15 are varranged check valves 1G which open underthe pressure-ofthe fuel' being pui'mliedl into the engine-'cylinders bythe compression oipuinping mechanism hereinfbefore describedaiidiwhiclicloses between fthe' working strokes ofcthe pumping' mech- 1 tolpreventthe escape'` of the fuel from the engine c'ylinder. In the casings 15are als 'arranged screens 17 through which the fuel passes beforeentering the engine cylinders, said screens tending` to break up orvaporize the fuel when forced therethrough.

Arranged n an extension of the top 3 of the cylinders is an automaticfuel measuring and dischargingr mechanism by means of which the 'properquantity of fuel is admitted to the cylinders for priming the same. Themeasuring and discharging mechanism comprises a measuring chamber 18 anda discharging chamber 19. The chamber 18 is provided in its lower end-With a fuel inletport 29 to which is connected a fuel supply pipe 21leading to a fuel supply1 tank "board-'or secured to the .dashother-suitable part of the vehicle.

pipe 21 is arrangedfacut off valve 23 whereby t-heflow of fluid from thet-ank maybe controlled. In the inner end of the port of the chamber 18is formed a valve seat with which is engaged a needle valve 24, the-stem25 of which projects upwardly through. a stuffing box in the to -of thechamber 18 as shown.4 Inoue si( e of the chamber 18 near its upper endisformed an air vent 26which permits the escape of air from the chamberand thus permits thefuel to flow into the chamber. In the partition ordividing wall between the chambers 18 and 19and at the bottom of saidwall is 'formed a passage 27 through whichthe fuel from the chamber 18is permitted to-tlow into the discharging chamber 19.

In the bottom' of the chamber 19 is formed a discharge port 28 to,whiclris connected a fuel conduct-ing pipe 2 9 theopposite end of whichis connected with a plurality of fuel inlet ports 39 formed in the base2, said ports having tlieir outer ends opening into the cylinders 1 asshown. In `the outer ends of the ports va,lve seats with which areengaged check valves 3l, saidvalves opening under the pressure of thefuel when drawn into the cylinders 1 by the upward strokes of thepistons 4,` thus permitting the fuel to be drawn'into the cylinders,said valve closing the fuel to be compressed and .forced out. through'the dischar e ports 12 past the *lvalves 13 and througi the fuelconducting pipes 14 lto the engine cylinders.-`

In the inner end of the port. 28 in the bottom of the chamber 19 isformed a valve seat with which is enaged a need-le valve 32, the stem ofwhic Works through a stuffing box formed in the top of the cham Y Inorder to alternately open and close the valves 24 and 32 to measure anddischarge the fuel from the tank or reservoir 22, I provide avalveoperating lever 38 which is pivotally mounted 'in a bracket 34arranged on the top plate of the chumplate through the po1t,28` InV the'30 are formedon the down stroke of the pistons to permitl bers 18 andA1.19 as shown. In the lever 33 a on op Jositc sides of its pivotalconnection l with the bracket 34 are formed -slots 35 with l which istems of the needle valves 21 and 32 wherehywhen said lever 33 isrocked, one of said Il valveswill he opened and the other closed.

i The lever is provided with a downwardly projecting extension 36between the lower end of which and the adjacent side Iof thc chamber 19is arranged a coiled spring 37. The pressure of the spring 3T "isexerted to actuatc the lever 33 in.V the Iproper direction for closingthe valve 24 i and opening the valve 32 thus permitting l' the `fuel topass from the chamber 19 and the pipe 29 to the l .ports 30 from whichit is drawn out through 'the valves 3l into the compressing chambers 1on the upward strokes of the pistons as hereinbefore described. ()n thelower end of the extension 3G of the lever 33 is formed a lug-38 withwhich the lever 8 is adapted to engagewhen .said lever is pushedforwardly to a sutticient extent.v In thus engaging the lever 8 with thelu'g 38 the i lever 33 will be rocked against the pressure of the spring37 and in the proper direction for closing the discharge valves 32 ofthe chamber 19 and opening the valve 24 of the chamber 18, thuspermitting the fuel to flow from the tank 22 into the chamber 18. Aslong as the lever 8 is held in a forward position the valve 24 will beheld open, thus pern'iitting the desired quantity of fuel to flow intothe chamber 18. When the chamv ber 18 has filled with fuel as will b eindi- -cated bythe overflow of the fuel through the vent 26, the lever 8is swung back, thus vreleasing,r the lever and permitting the spring 3Tto actuate the same and close the valve 24 and open the discharge valve32. As the lever 8 is pulled farther back the pistons 4 in the cylinders1 will he drawn upwardly through the medium of the har 9 and link l()thus sucking the fuel through the port 28, pipe 29, ports 30 and YcheckVvalves 31 into the cylinder 1. lhen the lever 8 is again pushedforwardly the bar 9 and link. 1() will be actua-ted to force the pistons4 downwardly in the cylinders 1. thus .fompressing and forcing the fuelfrom lsaid cylinders through'the discharge ports 12 and fuel conductingpipes 14 tothe engine cylinders as hcreinbefore described. thusprovidingI said cylinders with a priming charge. which is ignited andexploded b v any suitable sparking mechanism thus i starting the engine.

From the foregoing description-taken in connection with the'accompanying drawings, the constructionand.operation of the .inventionwill be readily understood without requiring a more extendedexplanation. Va rions changes in the form, proportion are connected theupper ends of the llt;

. tor each cylinder ot' the engine,
